Each carriage has a V-shaped notched into which a boat is fitted and is carried therein. Each carriage is fitted with rotatable subassembly carriages. Each subassembly carriage is fitted at their underside thereof with at least three caster wheels. The casters rotate 360° and the subassemblies also rotate 360°. As a result the entire dolly is able to rotate 360° about a central vertical axis.
